TORPEDO-GRENADE.

EPEGZFEGATI QQTJI forming part of Letters Patent No. 769,884, dated September 13, 1904. Application filed January 27, 1904. Serial No. 190,863. (No 11101161.)

T0 (ZZZ mil/071a may concern/.-

Be it known that 1, AUGUST BAUMGART, residingat Ucrnlea, in the county of Platte and State of Nebraska, have invented certain useful improvements in Torpedo-Grenades; and I do l'icreby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanyingdrawings, which form a part of this specification.

This invention relates to a new and useful improvement in torpedo-grenades The aim of my invention is to provide a grenade which will be constructed so that an exceedingly high explosive may be used.

My invention comprises certain combinations, as will be set forth more particularly in the claim.

In the accmnpanying drawing 1 have shown a central sectional view of a grenade embodying my invention.

In carrying out the aim of my invention 1 provide a suitable shell or casing'A, pointed at one end to form the breast 2, which is provided with the threaded neck 18, while the rear of the shell or casing is int'eriorly threaded, as at 12, to receive the cape, which is provided with a perforation, as is shown in the drawing. This shell or casing A is made of any suitable size and in front is perforated with two perforationsfi and 6 at suitable points at the breast, Wl'llC-l'l perforations are closed by means of the plugs 7. The rear cap a is provided with. the shoulder 9, adapted to receive the cap 8, while surrounding the opening 1 is a rounding the receptacle B, as is disclosed in the drawing. Positioned transversely within the forward end of the receptacle B is a bar 14, upon which bar is held a detonating-cap 15. this cap, as well as the bar 14, being intended to be entirely surrounded by the explosivesuch as dynamitafor instancewithin the receptacle B. Extending from this bar 14 is atube 16, forming a housing which projects through the receptacle B and at its forward end rests adjacent the inner point of the shell or casing A, as shown in the drawing. Held Within this housing 16, which is slightly enlarged centrally, as shown at 1'7, is a firing-pin 4:, projecting beyond the housing 16 and through the neck 18, projecting beyond the outer shell or casing, as shown, and this projecting end of the firing-pin is protected by a stout cap 19, threading upon the collar 18, as shown. This firing-pin 4: is provided with a stop if, against which works a spring 2-0, normally forcing the firing-pin forward, so that the lower end thereof will beheld away from the ,detonating-cap 15.

The rear cap 8 is seciired to the outer shell or casing A by means of a soft solder adapted to melt at a thermal point considerably below the heat generated within the piece at the time the shell is discharged.

Now in the use of this shell or grenade the plugs '7 are removed before lowering the same or before the shell is inserted within' the piece. At the moment of discharge the heat generated within the piece will be sufficient to melt the solder holding the cap 8, so that the spring 10 will promptly throw off this cap" 8, uncovering the vent or exit opening 1, so that in its passage through space a current of air will pass through the shell between the casing and in the receptacle, finding an escape at 1. tion the forward cap 19 is crushed, forcing the pin 4: inward to discharge the detonatingcap 15 and igniting the explosive within the shell.

These. shells, or grenades may be made of suitable sizes and are also adapted to he dropped from above.

, Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

A shell or grenade, comprising an outer On coming in contact with an obstruccasing perfomfiednear the forwardend, acap beyond the furward 'endofboth casings; and 1 v sumqeundingair-space.,means to support said I adaptedto bedisplaced-atthemoment;of1eava cap protectingthe farwzzrd end of said fir- I I I I ingzthe pieceto uncovez a rear vent-spelling; ingpin, all arranged subsmmiaiiy for I Ran interim explosivemontaining receptacle vthe pfirpose set im'th.
